Neighbors complaining of drug activity on their Hollywood street alerted police to a house where vast quantities of fentanyl, heroin and other narcotics were being peddled by a convicted drug trafficker, an arrest report said.

Aquile Ballate, 47, was arrested Friday at his home in the 800 block of North 11th Avenue. He is being held in a Pompano Beach jail, records show.

Police confiscated 21.3 grams of fentanyl, 11.8 grams of heroin, 2.8 grams of cocaine and .5 grams of methamphetamine from the residence, the report said.

Ballate was charged with numerous drug-related counts, including fentanyl and heroin trafficking.

Fentanyl is a synthetic drug that has a similar effect to heroin. It's so potent it is sometimes used to tranquilize elephants. Prescribed to cancer patients for decades, fentanyl is the most powerful painkiller available. It is up to 50 times more potent than heroin, and up to 100 times stronger than morphine, experts say.

Ballate is currently on probation through Nov. 27, 2019, for stealing a car in Miami-Dade County, records show.

He is the second person Hollywood police have arrested on fentanyl-trafficking charges in two weeks.

A woman who Hollywood police say was responsible for flooding their streets with the potentially lethal mixture of heroin and fentanyl was taken down in a drug sting after making her third sale to a confidential informant, arrest records show.

Ayesha Narona Henry, 29, sold drugs to the informant...

When they arrested Ayesha Henry, 29, on Feb. 1, she had 21 bags of the drug in her car, police said. She sold drugs to a confidential informant three times, police said.

The complaints about the frequent activity at Ballate’s house began in January, according to a police report.

While Ballate was under investigation, police pulled over someone leaving his house with 14 grams of heroin, the report said. That person, whose name was not included in Ballate’s arrest report, told police they had just bought the heroin from Ballate and they had been doing so for the past year, records show.

Ballate has served three stints in Florida state prison for convictions on cocaine possession and cocaine trafficking, records show.
